v0.3.0-alpha

• Fix issue running a window function without any partitioning but with a window size defined.

v0.2.7-pre-alpha

• Add .pivot() DataFrame method for transposing data.
• Fix breaking change in mocha test runner after version update.

v0.2.6-pre-alpha

• Add DataFrame functions:
  • size()
  • regexReplace()
  • replaceAll()
  • replace()
  • leftAntiJoin()
  • rightAntiJoin()
  • fullOuterJoin()
  • unionByName()
• When a DataFrame is created, properties of all row objects are checked against the set of specified columns.
• Fix for errors generated by DataFrame.withColumn("col", fn) and DataFrame.filter(fn) when fn calls a method of a column value object. For example, when a column latest_date is of type Date, then doing something like: df.filter((row) => row["latest_date"].toISOString().split("T")[0] == "2023-02-06") or df.withColumn("derived_date", (row) => row["latest_date"].toISOString()) would generate an error. This was due to the function validateFunctionReferencesWithProxy that checks the column references made by the function using a Proxy object.

v0.2.5-pre-alpha

• Refactor window() to be called from within withColumn()
• Add window functions:
  • mean()
  • median()
  • quantile()

• Add tests for withColumn() function
• Add tests for fromArray() function
• Improve checking for joins (e.g. overlapping columns so that joins do not overwrite data, non-existing column references, ...)

base

This release simply dumps the current state of the lorix package as a base release for any pre-alpha testers.

The package is very much still in development mode so consider the API and functionality in draft stage, and subject to change in the future.
